China has become the world's largest producer of antipyretic and analgesic drugs. The output of aspirin, paracetamol, and analgin is over 10,000 tons. The yields of phenacetin, aminopyrine and antipyrine are over 1000. Ton. At present, the output of antipyretic and analgesic drugs in China is growing rapidly, and it is expected to grow at a rate of about 8% in the future. The production of intermediates for the production of antipyretic and analgesic drugs is large, and there are many manufacturers. With the growth of antipyretic and analgesic drugs, its intermediates have also achieved considerable development.
In 2003, domestic consumption of paracetamol increased rapidly, and exports also showed rapid growth. The export volume was 28,163 tons, and the annual export volume increased by about 1 time. Although the export growth rate slowed down in the first half of 2004, it still increased. The export volume of paracetamol in January-May 2004 was 12,501 tons, slightly higher than the same period last year. Para-aminophenol is an important intermediate for the synthesis of paracetamol and has also grown rapidly in recent years. At present, the annual production of p-aminophenol in China is about 32,000 tons. It is estimated that by 2005, the domestic production of paracetamol will reach 50,000 tons, and the pharmaceutical industry will consume 45,000 tons of p-aminophenol, plus in other fields, 2005. The total annual demand for p-aminophenol is about 50,000 tons, the market gap is large, and the development and utilization prospects are broad.
